Our laboratory combines the research fields of decision science such as neuroeconomics, behavioral economics, and psychology. In addition to these research fields of individual decision making, we will extend and connect principles of decision making to decision making at group and society levels with the aid of analysis techniques of big data, which are developed in new fields of collective behavior. Our research will bring about positive impacts to people in society by enhancing scientific understanding of humans and by creating sustainable designs of social systems. Through this exciting research endeavor, we create positive values for people in our global society.

For more information, read the interview article “Good decisions and good science both start with honesty” here.

We are largely supported by the RIKEN Center for Brain Science and Toyota Motor Corporation. Our mission is to do both fundamental academic neuroscience, and hopefully contribute meaningful research knowledge to the larger society.
